A time-of-check to time-of-use (TOCTOU) vulnerability has been identified in the container runtime, Containerd, specifically in version 2.1.0. This vulnerability occurs during the unpacking process of container images pulled from repositories, allowing specially crafted images to make arbitrary modifications to the host filesystem. Users of Containerd are advised to upgrade to version 2.1.1, which addresses this issue.
